Our invention relates to foldable extension counter shelves that areadapted to be fastened to a store counter for the convenient purpose ofretaining roceries such as bread,

5 cakes and the like. (llartain obi'ects'oftheinvention are to provide ashe f comprising novel means for securely clamping the device to a storecounter; novel means for retainin the side and end frames of the devicelocke in the upright position; novel means whereby the device is foldedin compact form; and novel means for securing the device in the foldedposition.

With the above and other objects in viewwhich will appear as thedescription proceeds, the invention consists of the novel construction,adaptation, combination and arrangement of parts hereinafter describedand claimed. These objects are accomplished by devices illustrated inthe accompanying drawing; wherein Figure 1 is a view in end elevationshowing the device attached to a counter;

'Fi 2 is a general view'in perspective of the evice; and

Figure 3 is a view in perspective showing one end portion of the devicein the folded position.

Referring to the drawing throughout 80 which like reference numeralsdesignate like parts, the bottom of the shelf comprises a rectangularwire frame 5 having a plurality of transverse bars 6 secured thereto 1nspaced a art relation. Spring bracket clamps have t 1eir upper portions7 welded or otherwise secured to the underside of the bottom at each endthereof. Said clamps are bent upon themselves to form lower portions 8whose outer ends are bent inwardly to form heel portions 9 and toeportions 10. A bolt 11 passes loosely through the lower portion of eachclamp and is secured to the upper portions thereof at 12 in any suitableand desirable manner.

A butterfly or other form of thumb nut 13 is installed on the bolts 11of the clamps. To install the device, as shown in Fig. 1, the inner halfportion of its bottom is placed on the top 14. of a, counter with thetoes 10 of the clamps engaging the underside of the overhanging portionof the counter, and the heel ortions 9 of said clamps bearing againstthe orward upright face of said counter.

The nuts 13 are then screwed up thus draw ing the lower portions 8 ofthe clamps toward their upper port-ions 7 and causing their heel and toeportions to securely engage the counter. This clamping arrangement 1ysecured to a counter and with suflicient ro- 5 vides means whereby thedevice may be rmrigidity to supfport the load thereon even though most 0the load be placed on the olflter or forward overhanging portion there-0 The two side frames of the device each comprise a longitudinal bar 15whose end port1ons are bent upwardly and downwardy upon themselves toknobs 16 and depending legs 17. The ends of said legs are pivotallysecuredto the bottom frame 5 by means of loops 18. The two ends framescomprise transverse bars 19 provide upstanding whose outer end portionsare bent upon as a whole locked in an upstanding rectangular position asmost clearly shown in Fig. 2 of the drawing.

To fold the device asshown in Fi 3, the end frames are first raised andtheir loops 20 are freed from. the knobs 16. Said end frames are thenslidabl lowered until their loops 22 impinge the oops 18 of the sidelegs 17. The side frames are then pivotally folded inward until theirbars 15 rest on the transverse bottombars 6. The end frames are thenfolded inward until their bars 19 rest on the side bars 15. B of slightforce the loops 20 of the en frames are sprung or snapped under thesides of means I tures. 60

. the bottom frame 5 thus securin all of the side and end frames in thefol position whereby the device as a whole is disposed in a very com actform.

5 Having t us described our invention, it be-,

ing understood that minor changes in its con- ,struction and arrangementmay be resorted w 'to. without departing from the scope and s irit ofthe invention, what we claimand de- 10 sue to secure by Letters Iatentof the United States is 1. The combination of a foldable shelf of thecharacter described with the forward ortion of a store counter, ofclamps secured to the bottom end portions of the shelf, said clamps bentto form lower sprin portions, said lower portions bent inward y to formheel. and toe portions, a bolt passing loosely through the lower springportions and hav- 90 ing a nut arranged to compress said lower springportions, and the rear bottom portion of the shelf resting on the top ofthe counter with the toe and heel portions of the clamps respectivelyengaging under the overhanging top portion and against the front face ofthe counter.

2: A foldable extension counter shelf having in combination arectangular bottom frame with transverse bars secured thereto,

side bars having upstanding knobs and depending legs, said legs havingloop ends pivotally connected to the bottom frame, end ars having loopsadapted to fit over the upstanding knobs whereby the side bars areretained in parallel spaced apart relation, depending legs for the endbars having loop ends slidably disposed on thelegs of the side bars, andclamping means whereby the shelf may be secured to a store counter.

3. A foldable extension counter shelf having in combination arectangular frame with transverse bars, side frames comprising alongitudinal bar, upstanding knobs and dependin legs, said legs havingloop ends pivotal y connected to the bottom frame, end

frames comprising transverse bars with loops spaced apart to fit overthe upstanding knobs when the frames are in the upright position, saidend frames having depending legs with loop ends slidably mounted on thelegs of the side frames, clamps secured to the bottom end portions ofthe shelf, said clamps bent to form lower spring portions and heel andtoe portions, and a bolt passing 55 loosely through the lower springportions and having a nut adapted to compress said lower springportions.

In testimony whereof we aifix our signa- LEVI J. MURPHY. ERNEST L.STAUFFER.
